💖 decode-dimms — the manual page, but make it cute 💖

okay bestie, welcome to decode-dimms(1) from the i2c-tools fam — this is a User Commands situation and she is iconic. basically: she decodes the info chillin' inside memory module SPD EEPROMs, and she's gonna tell you everything. no gatekeeping fr fr 🫶

✨ NAME ✨

decode-dimms — decode the information found in memory module SPD EEPROMs 💅

🌸 SYNOPSIS 🌸

decode-dimms [-c] [-f [-b]] [-x|-X file [files..]]
decode-dimms -h

🦋 DESCRIPTION 🦋

so like, the whole point of the decode-dimms tool is to decode the information found in memory module SPD EEPROMs. that's the vibe. that's the mission. 💖

the SPD data gets read either from the running system or from dump files. two paths, both slay.

but listen — in the running-system case, the tool needs a kernel module to be loaded, and the options are: eeprom, at24 or ee1004 (that last one is for DDR4 SDRAM.) so like, load one of those first or she's just gonna sit there like 🙈

🎀 PARAMETERS 🎀

  • -f, --format — print nice html output ✨ (yes, she can serve html, main character energy)
  • -b, --bodyonly — don't print the html header. super useful for postprocessing the output, iykyk 🧚
  • --side-by-side — display all DIMMs side-by-side if possible 👑
  • --merge-cells — merge neighbour cells with identical values. this one is side-by-side output only, and it's the default, periodt
  • --no-merge-cells — don't merge neighbour cells with identical values. again: side-by-side output only, bestie
  • -c, --checksum — decode completely even if the checksum fails. like, she's decoding anyway, no cap 💀
  • -x — read data from hexdump files
  • -X — same as -x except treat multibyte hex data as little endian 🔥
  • -h, --help — display the usage summary 🫶

😭 BUGS 😭

got a bug? found a fix? pls don't suffer in silence. write to the Linux I2C mailing list <linux-i2c@vger.kernel.org> with a Cc to the current maintainer: Jean Delvare <jdelvare@suse.de>. she'll see it, she'll fix it, we move. 💜
